SEARCH: Test my I.M.O.C.A to the start of the Vendee Globe 2024.

- 1995 Project for the 1996-97 Vendee Globe Race. Designed with a single chine, with straight daggerboards and a rotating keel, mast, and wishbones.

- With just a year to go before the start of the Vendee Globe, and with the Transat Jacques Vabre underway, let's make the point as of now and for the future IMOCAs over the next 12 months. I have no access to files about the newly launched boats, and therefore I will start with my own evolution with designs for this very special Class.
- Eventually, with the progress and comments going to be made, I might change my ideas to present a coherent and up-to-date approach to my own vision.

- Well, this year has been something else. I found myself so busy that I had no time to follow through with the Vendee Globe; to write my own vision about the IMOCA evolution, besides the fact that it is over my head at the moment, having no access to the tooling necessary to elaborate this foiling era for the Class.

- Eventually, I'll get back with my interpretation.

-Well! Too late. Pressure at work and the total foils revolution, I have not been able to follow through as I said above. As the boats are approaching the finish line in an unprecedented close race for the Vendee Globe, I definitely reserve my comments and my own observation about what is going on.

The early years of Yacht Designs by TANTON.

- Above drawing.

- My first One-Tonner design. At the time, when the R.O.R.C (Royal Ocean Racing Club). Rules dictated the Ocean handicap system and Offshore racing in Europe.

- In 1968, during my Military Service, obligatory at the time, I was fortunate enough to be detached from the Bataillon de Joinville, and able to join A.F.C.A (Association Francaise pour la Coupe America). Balancing my time between sailing 12 Metre, working for A. Mauric and Britton Chance; and tank testing a string of 12M.

- From a design point of view, and the highlight at the A. Mauric Studio was tasked with reproducing Intrepid, S&S America's Cup winner, from 2000 photos with the rating certificate. Also, a 50ft. cruising boat. Unfortunately, the owner, a pilot, crashed in Martinique.

- In my spare time, I designed several boats, including this One Tonner, heavily influenced by a drafting method developed by A. Mauric, before computers, of course, by the development Class of the 5.5 Metre. Compared to Tina, the boat is more conservative in its deadrise, balanced hull lines, and other features.

- But, before all of this, came the One-Tonner Tina.

- In the 1966 One Ton Cup in Denmark, a certain Tina, a Dick Carter design, beat all professional yacht designers.

Personally, I was the skipper of the Illingworth & Primrose design Maryka, coming in 12th. In the fleet of 24 yachts, I knew that the wind was changing, and the change was Dick Carter.

- Officially, I established Tanton Yacht Design at the beginning of 1974. Of course, it was a big jump from one of the best Yacht Design Firm in the world, where for 3 and 1/2 years I had been the Design Director, directly involved with the drafting of very famous boats. The move from Nahant and Marblehead was to come down to Newport and start from scratch, and... wait.

- Having not stolen any customers, this could have been a long time in waiting. Doug Peterson wanted me to join him in San Diego and Charley Morgan in Florida. Fortunately, before too long, small commissions came in, and eventually, with an order for a One-Tonner.

- The Preliminary Design.

- The Design, including tank testing at M.I.T., with Professor Kirwin and J Milgram, led to Marrakesh Express, the aluminum Palmer-Johnson built One-Tonner. TYD#743,

A good-looking one, if I can say so!

- Love Machine 2. Also built by Palmer-Johnson, Wisconsin, followed. TYD#744.

- Quarter Tonner Clavier.

- 38'Epee.

- Quarter Tonner Pantaia.

- 28' M.O.R.C Woodwind.

- Two Tonner Black Gold.

- Building BlackGold.

- Kachina.

- Building the Half Tonner Kachina, next to the Two Tonner Black Gold. Katrina had an elongated skeg with the spade rudder underneath. This is to increase the volume low, otherwise lost with her pin tail stern configuration.

- Typical masthead rig for Katchina half-tonner of that era.

- Scaramouche. Merle Hallett's 42'.

- Mini Ton.

- Anitra 60'.
- Designed for the Whitbread Round the World Race 1977-1978.
Unfortunately lack of funds prevented from taking part, with the same scenario happening for the next 1981-1982 Race. I think she might have been a strong contender.

- Notice the C-Flex method of construction. Popular a while ago, and a strong way to build a boat. The drawback is that it is a little heavier than in other conventional ways because the woven pattern of the rods between the E or S-glass fibers tends to collect more resin. You can see in the pictures that a single partition in the middle maintains the rigidity of the hull.
